+\H{changeM}\i{Change Menu}
+
+\G{png.d/mchange.png}
+
+The \f{Change Menu} has all functions related to modifying objects that exist on the layout drawing.
+
+\dd \f{Change Scale} - change model scale and / or gauge of layout design. (\K{cmdRescale})
+
+\u000
+
+\dd \f{Clear Elevations} - remove elevation parameters from selected track(s).
+
+\u000
+
+\dd \f{Connect Sectional Tracks} - creates a connection between sectional track pieces by slightly moving the select piece(s) and the pieces they connect to.
+
+\u000
+
+\dd \f{Elevation} - define an elevation at specified track location (\K{cmdElev}).
+
+\u000
+
+\dd \f{Flip} - turn selected object(s) over or around.
+
+\u000
+
+\dd \f{Join} - connect two separate pieces of track. This command can be used to move one of the pieces of track to the endpoint of the other or to create a connection by laying a stretch of flex-track.
+
+\u000
+
+\dd \f{Modify} - modify an existing track.
+
+\u000
+
+\dd \f{Move} - move selected object(s).
+
+\u000
+
+\dd \f{Move Description} - move the endpoint description of a track piece to another location.
+
+\u000
+
+\dd \f{Profile} - display the elevation profile of a definable stretch of track (\K{cmdProfile}).
+
+\u000
+
+\dd \f{Properties} - sets \e{XTrackCAD} into \e{Describe} mode. Whenever an object is clicked on while in this mode, the \f{Properties} dialog is opened. This dialog allows direct manipulation of settings such as the objects length, position or orientation.
+
+\u000
+
+\dd \f{Raise/Lower Elevations} - raise or lower elevation of selected tracks.
+
+\u000
+
+\dd \f{Rotate} - rotate selected object(s).
+
+\u000
+
+\dd \f{Recompute Elevations} - performs a global re-computation of dynamic elevations. It should not be necessary to issue this command as elevations are recomputed as required.
+
+\u000
+
+\dd \f{Select} - sets \e{XTrackCAD} into \e{Select} mode. Whenever an object is clicked on while in this mode, this selection state of this object is reversed. If an object was unselected it becomes selected, and vice versa. To unselect all objects press the ESC key, use \f{Deselect All} from the \f{Edit} (\K{editM}) menu or \f{Deselect All} from the \f{Pop-up} menu (\K{mouseBcmd}).
+
+\u000
+
+\dd \f{Split Track} - the \f{Split Track} command can be used in one of two ways;
+
+\lcont{
+
+\u000
+
+\b split a section of flex-track into two connected pieces at the point where a \e{Left-Click} is invoked or;
+
+\b disconnect turnouts or sectional track pieces at their point of connection.
+
+}
+
+\rule
+
+
+\S{cmdRescale} Change Scale
+
+\G{png.d/rescale.png}
+
+\f{Change Scale} is used to change the size and gauge of selected (\K{cmdSelect}) objects. The amount to resize can be specified
+
+\u000
+
+\b by the modeling scale, e.g., convert from HO to O scale
+
+\b by the modeled gauge, e.g., convert from standard gauge to narrow gauge, or
+
+\b by ratio (by 181.5%).
+
+If resizing by modeling scale then track dimensions, e.g., lengths and radii, will be changed as well. An option is available to disable the resizing of the selected objects.
+
+\rule
+
+
+\S{clrElev} Clear Elevations
+
+The \f{Clear Elevations} command is used to remove elevation points from selected track on the layout.
+
+Using the \f{Select} command, select the track that is to have its elevation settings cleared then select \f{Change>Clear Elevations} from the menu bar to clear elevations of selected track.
+
+\rule
+
+
+\S{cmdConnect} Connect Sectional Tracks
+
+\G{png.d/bconnect.png}
+
+This command is used exclusively with \e{Sectional Track}.
+
+Occasionally pieces of sectional track do not line up exactly, especially when creating figure-8's or passing sidings. When laying out the actual track you can compensate for this by adjusting the individual tracks to provide a bit of slack. This command simulates that process.
+
+Click on the endpoint of each track you're trying to connect. Tracks will move slightly in an attempt to overcome the gap. If the gap is too large, the connection will fail. If this occurs, try using other track pieces in your layout.
+
+\e{XTrackCAD} adjusts the positions of tracks connected to the tracks up to a track with more than two connections. See the Demo for details.
+
+If one (or both) the selected tracks is an adjustable section (such as Kato's Adjustable Track #20-050) then the length of the track is changed to fill the gap.
+
+You can undo the effect of the \f{Connect} command by splitting (\K{splitDisconnect}) the track to disconnect it then using the \e{Shift+Left-Click} \f{Connect} command on the unconnected endpoints to tighten connections between the tracks.
+
+\rule
+
+
+\S{cmdElev} Elevation
+
+\G{png.d/belev.png}
+
+The \f{Elevation} command changes the elevation of track endpoints. After opening this dialog, you can click on the respective endpoint to set its elevation properties. The endpoint on which you work is indicated with a big red dot.
+
+\G{png.d/celev.png}
+
+An endpoint can have one of several elevation types:
+
+\u000
+
+\b \f{None} - no elevation defined.
+
+\b \f{Defined} - a defined elevation at a specified height.
+
+\b \f{Hidden} - a defined elevation but not displayed on the layout.
+
+\b \f{Computed} - height is based on height of closest neighbors.
+
+\b \f{Grade} - grade is based on height of closest neighbors.
+
+\b \f{Ignored} - endpoint is not considered in computations.
+
+\b \f{Station} - assigns a name to the endpoint.
+
+\f{Note:} Only one of these attributes can be assigned to an endpoint. For example, an endpoint can not be defined as a Grade and a Station at the same time.
+
+When an endpoint is selected on the layout by \e{Left-Click}, it is highlighted by a large red dot and its elevation type and values are displayed in the dialog.
+
+Additionally, \f{Defined Elevation} endpoints are indicated on the layout by gold colored dots. \f{Ignored Elevation} endpoints are indicated by blue colored dots.
+
+\e{Shift+Left-Click} splits the track at the specified point and adds an elevation point.
+
+The grade at the specified endpoint is displayed next to the \f{Grade} radio button. For \f{Defined Elevation} endpoints, the grade on each side of the endpoint is displayed.
+
+\f{Defined Elevation} endpoints are used to specify fixed heights of track endpoints. Typically, this would be where a grade changes or where clearances must be maintained. \f{Computed} Elevations and \f{Grade} markers can place between \f{Defined Elevation} endpoints. These values are not entered directly but are computed dynamically based on \f{Defined Elevations} of connected tracks. This allows labeling of elevations at intermediate endpoints without having the enter specific values. \f{Computed} markers can also placed between a \f{Defined Elevation} point and the end of a track.
+
+\f{Stations} are used to provide information for the Profile (\K{cmdProfile}) command.
+
+All \f{Elevation} labels (including \f{Grade} and \f{Station}) are drawn on the layout in outlined boxes. These may be moved by the \f{Move Description} (\K{cmdMoveLabel}) command. In addition, \f{Grade} labels have an arrow indicating the upwards direction.
+
+\rule
+
+
+\S2{computeElevations} Computing Dynamic Elevations
+
+Elevations of Tracks are computed in following steps. The colors listed in each step are used as the background color of the Track Elevation Markers (if they are enabled (\K{cmdDisplay})).
+
+\b The Shortest Paths between all \e{Defined Elevations} are computed. A Path stops at \e{Ignored} or \e{Defined} endpoints. The Elevation of any Turnouts on these Paths with more than two connections are computed as the average Elevation inversely weighted by distance along the tracks to the \e{Defined Elevation} points (\e{Blue}).
+
+\u000
+
+\b The Elevation of any other tracks on the Shortest Paths are computed based on the distance along the tracks from the Turnouts computed in the first step and/or the \e{Defined Elevation} points (\e{Purple}).
+
+\u000
+
+\b The Elevation of any remaining tracks is computed based on the average Elevation of the tracks found in the first two steps that they are (directly or indirectly) connected to, inversely weighted by geometric distance (\e{Gold}).
+
+\u000
+
+\b Any remaining tracks are not connected to a \e{Defined Elevation} and do not have an Elevation.
+
+The elevation computation is performed incrementally every time the layout is changed to keep all elevations in sync. The performance of the computation is affected by the placement of the \e{Defined Elevation} endpoints and the number of Paths between them. Place the \e{Defined Elevations} at points where tracks begin to branch (such as the throat of a yard or at the ends of a siding). Also, use \e{Defined Elevations} to break the layout into areas so recomputation has fewer tracks and Paths to deal with.
+
+\rule
+
+
+\S{cmdFlip} Flip
+
+\G{png.d/bflip.png}
+
+This command turns selected objects over or around, effectively mirroring the object .
+
+\n Prior to invoking this command visualize how the selected object(s) will be flipped and determine where to draw a reference line that will act as an axis or anchor point for the flipped object(s).
+
+\lcont{
+
+\u000
+
+\dd \G{png.d/flip1.png} \G{png.d/flip2.png}
+
+\u000
+
+}
+
+\n Invoked the \f{Flip} command then \e{Left-Click} on one end of the reference line visualized in the proceeding step. Holding the \e{Left} mouse button, \e{Drag} the cursor across the layout to form the line visualized earlier.
+
+\lcont{
+
+\u000
+
+\dd \G{png.d/flip3.png} \G{png.d/flip4.png}
+
+\u000
+
+}
+
+\n Once a line of desired length and orientation appears, release the mouse button. The selected object(s) will then flip around the line as if it were a mirror.
+
+Since flipped objects are mirrored, turnout titles may be modified during the flip process. Right hand turnouts will become left hand turnouts and vice versa. Such is the case in this example.
+
+Certain turnouts, such as a Wye's, Three-Way or Crossings are symmetrical and thus titles for this type of objects are not changed. If a title change is necessary the currently loaded \f{Parameter Files} (\K{cmdPrmfile}) are searched for a turnout that matches the flipped turnout. If a match is not found, the turnout's title is prefixed with \f{Flipped}. The \f{Properties} (\K{cmdDescribe}) command be used to change the title of such turnouts.
+
+\rule
+
+
+\S{cmdJoin} Join
+
+\G{png.d/bjoin.png}
+
+The \f{Join} command is used to bring together and connect any two segments of track. During the join process, \e{XTrackCAD} ensures the connecting tracks are properly aligned.
+
+See \f{Help>Demo} (\K{cmdDemo}) for examples of how to join tracks.
+
+For detail about;
+
+\dd Using curved flex-track to join track segments refer to \K{joinTrackCurve}.
+
+\u000
+
+\dd Using straight flex-track to join track segments refer to \K{joinTrackStraight}.
+
+\u000
+
+\dd Moving one segment of track to join with another refer to \K{joinTrackMove}.
+
+\rule
+
+
+\S2{joinTrackCurve} Using Curved Flex-Track
+
+This method of joining track may be used where tracks are joined with a 'simple curve', e.g. one which uses a curve in a single direction as opposed to using reverse curves (\K{generalTerms}).
+
+\u000
+
+\dd \G{png.d/joincrv1.png}
+
+\u000
+
+\n Start the join process by clicking on the Join button (\G{png.d/bjoin.png}).
+
+\lcont{
+
+\u000
+
+\G{png.d/joincrv2.png}
+
+\u000
+
+}
+
+\n \e{Left-Click} the endpoint of one of the two tracks being joined. A red dot will appear as a reminder of which track has been selected.
+
+\lcont{
+
+\u000
+
+\G{png.d/joincrv4.png}
+
+\u000
+
+}
+
+\n Move the mouse pointer over the endpoint of the other track then \e{Left-Click} and hold the mouse button down. A track connecting the two endpoints will appear. If the track appears in black (and you are happy with the curve as its drawn), release the mouse button.
+
+\lcont{
+
+\u000
+
+\G{png.d/joincrv3.png}
+
+\u000
+
+}
+
+\n If the track appears in red, it means \e{XTrackCAD} can't determine how to connect the first track with the second. If this occurs, while holding the left mouse button, drag the mouse back toward the first track until the connecting track appears in black. If the connecting track remains red, drag the mouse in the opposite direction until the connecting track turns black. Once the connecting track turns black, release the mouse button to finalize the \e{Join} command.
+
+\lcont{
+
+\u000
+
+\G{png.d/joincrv5.png}
+
+\u000
+
+}
+
+Throughout the above, the exact shape of the curve can be adjust by dragging the mouse around while keeping the left mouse button held down.
+
+Sometimes, no matter where you drag the mouse, the curve stays red and the tracks cannot be connected. This means the resulting curve is tighter than the minimum track radius set in the \e{Preferences dialog} (\K{cmdPref}). If desired, this setting can be adjusted from the \e{Preferences dialog} using the \f{Options>Preferences} menu selection to raise the dialog. If changing the minimum track radius is not a desired option then it will be necessary to relocate one of the tracks that you're attempting to join.
+
+You may also find that \e{XTrackCAD} will not create the connecting curve in the exact shape you want. If this happens it may be necessary to either move one of the end points or draw a partial curve (or straight) and try again.
+
+If enabled, Easements (\K{cmdEasement}) will be automatically generated between tracks of differing radii. When using easements, there is a minimum radius as specified in the \e{Easement} dialog. It's not possible to join tracks with less then this radius and the connecting track's radius must be greater than the minimum radius.
+
+If any errors occur while joining tracks (such as moving beyond the end of a track or using a curve with a radius smaller than the Easement radius), then the joint track will be drawn in Red (The default colour of Exception Track errors. See \K{cmdRgbcolor} for detail). This colouring serves as visual indication for a connecting track that doesn't meet minimum specified parameters (\K{cmdPref}).
+
+Any tracks created during the \f{Join} command will have the following properties inherited from the first track: selected state, hidden state, scale, track gauge and Layer.
+
+A join can be made to or from a circle (\K{cmdCircle}) of track. Joining a track with a circle will cause the circle to be converted into a curved track.

+
+When this command is used to join;
+
+\b two flex-track endpoints, one long section of flex-track without joints will result.
+
+\b two sectional track endpoints, a section of flex-track will be created between and used to join the two sectional track endpoints.
+
+\b one flex-track endpoint with one sectional track endpoint, the section of flex-track will be extended and joined with the sectional track endpoint.
+
+Any tracks created during the \f{Join} command will have the following properties inherited from the first track: selected state, hidden state, scale, track gauge and Layer.
+
+Turnouts and Sectional (\K{cmdHotBar}) tracks can be joined to other tracks. \e{XTrackCAD} extends the selected endpoint with a straight track when making the connection.

+\S{cmdModify} Modify
+
+\G{png.d/bmodify.png}
+
+The \f{Modify} command is used to change characteristics of or extend existing track by adding new track. This command works with any unconnected track endpoint.
+
+The \f{Modify} command can be invoked using the \f{Change>Modify} menu item, the \f{Modify} button or the menu raised by a \e{Right-Click} over the \f{Main Canvas}.
+
+Either the left mouse button (for changing length or creating a tangent track) or the right mouse button (for extending with a new track) is used to modify the unconnected endpoint.
+
+The endpoints of a \e{Line}, \e{Dimension Line}, \e{Table Edge} or \e{Bench-work} can be dragged to new positions. A \e{Box} is treated as 4 Lines.
+
+\e{Curved Lines} are modified in same manner as curved track.
+
+Selecting a corner of a \e{Poly Line}, \e{Filled Box} or \e{Polygon} moves that corner to a new position, and if moved close to a neighboring corner will merge the two corners and delete the edge between them. Selecting an edge will create a corner that can be dragged to a new position.

+Successful use of this command requires selection of the object(s) to be moved before attempting to move it. An object is selected by using the \e{Left-Click} command. A group of connected objects can be selected using the \e{Shift+Left-Click} command.
+
+A pop-up menu with commands controlling how objects are drawn during moves can be activated by entering a \e{Shift+Right-Click} command while hovering over the \f{Main Canvas}

+\e{Left+Drag} is used to move the selected object(s) around the layout.
+
+\f{Note:} The \f{Draw Moving Tracks} Radio box on the \f{Command Options} (\K{cmdCmdopt}) dialog can also be used to select how objects are drawn during drags to move or rotate objects. The options for this feature are:
+
+\b \f{Normal} - objects are drawn normally. This can be time-consuming when using a slow machine and moving a large number of objects.
+
+\u000
+
+\b \f{Simple} - objects are drawn using one line (instead of two when zoomed in). Structures are drawn as outlines, no endpoints or lines are drawn.
+
+\u000
+
+\b \f{Endpoints} - only the endpoints are drawn (as stars).

+\S{cmdMoveLabel} Move Description
+
+\G{png.d/bmovedes.png}
+
+This command is used to move Elevation, Grade, Station (\K{cmdElev}), Curved Track (\K{cmdCurve}), Helix (\K{cmdHelix}) or Turnout (\K{cmdHotBar}) Labels.
+
+The \f{Move Description} command can be invoked using the \f{Change>Move Description} menu item, the \f{Move Description} button or the menu raised by a \e{Right-Click} over the \f{Main Canvas}.
+
+Click the \f{Move Description} button to activate the \f{Move Description} command. Use \e{Left+Drag} to move the label to a new position. Once moved, the label becomes fixed in a position relative to the object. Subsequent moves of that object will cause the label to move as well.
+
+This operation can also be invoked by \e{Ctrl+Left+Drag} when in Select mode (\K{cmdSelect}).
+
+\e{Shift+Right-Click} (\K{cmdAcclKeys}) can be used to toggle display of individual Curved Track, Helix or Turnout Labels.
+
+\rule
+
+
+\S{cmdProfile} Profile
+
+The \f{Profile} dialog draws a profile showing elevations, distances and grades for a path on the layout.
+
+\G{png.d/dcprofile.png}
+
+Choose a path by using \e{Left-Click} on endpoints. As each endpoint is chosen, the path is extended via the shortest route. Selecting the end of the path trims the path back to a last \f{Defined Elevation} point (if any, otherwise the path is cleared).
+
+If no route is possible an error message is displayed. There are several reasons why this might happen:
+
+\b The tracks are not connected. Check this by using \e{Shift+Left-Click} on one track using the \f{Select} command (\K{cmdSelect}). This selects all tracks connected (directly or indirectly). See if the other track is selected.
+
+\u000
+
+\b One of the endpoints on the route is \f{Ignored} (\K{cmdElev}). Look for blue dots on the expected path when using the Profile or \f{Elevation} (\K{cmdElev}) commands.
+
+\u000
+
+\b The only route connects to a section of track that is already on the path and is not the end of the path. Remove the end of the path until the connected track is not on the path.
+
+The path is drawn in the Profile Color (\K{cmdRgbcolor}) (default Purple) on the layout.
+
+If the shortest path is not what you want, you can choose endpoints that are closer to the end of the path. Also, you can \f{Ignore} (\K{cmdElev}) endpoints to prevent the path from choosing a route through that endpoint. Shift+Right-Click (\K{cmdAcclKeys}) displays a pop-up menu that allows you to change the specified endpoint to be a \f{Defined}, \f{Ignored} or \f{None} Elevation endpoint.
+
+Each \f{Defined Elevation} endpoint on the path is drawn as a Vertical bar, labeled with its height and distance from the beginning of the path.
+
+The \f{Grade} between points is displayed between the vertical bars. The \f{Grade} line is drawn in Blue if that portion of the path does not contain more than one Shortest Path between Defined Elevation endpoints. Otherwise it is drawn in Red, to indicate the grade is an average and the actual grade may vary for any particular track segment. See Computing Dynamic Elevation (\K{computeElevations}) for more details.
+
+\f{Stations} on the path are displayed along the bottom of the \f{Profile}.
+
+The heights of \f{Defined Elevations} can be changed by using \e{Left+Drag} on the profile window. As you \f{Drag}, the new elevation and grades to each side are displayed at the bottom of the profile dialog.
+
+The \f{Done} button closes the dialog.
+
+The \f{Clear} button preserves elevation settings established along the current profile path, removes all profile points and leaves the \f{Profile} dialog open for selection of the next set of profile points. This function is useful when there's a need to view elevations along multiple profile paths.
+
+The \f{Print} button prints the dialog. The aspect ratio is preserved on the print-out. You will probably want to print in landscape format.

+\S{cmdDescribe} Properties
+
+\G{png.d/bdescrib.png}
+
+Clicking on the \f{Properties} (Describe Mode) button cancels all active commands, closes any open dialog windows and places focus on the main window.
+
+A \e{Left-Click} on an object while in \f{Properties} mode causes a properties dialog window to appear. The properties dialog contains information pertaining to the selected objects position, size, color and layer as appropriate for each type of object. Certain values can be changed to modify the object. If a track is connected to other tracks, then some values, e.g., endpoint positions, can not be changed.
+
+\G{png.d/dproperties.png}
+
+The selected object is highlighted by a grey area.
+
+\G{png.d/dpropertieshighlight.png}

+Most commands return to \f{Properties} mode then they terminate unless the command is sticky (\K{cmdSticky}).
+
+Note: the Default Command radio button on the \f{Command Options} (\K{cmdCmdopt}) dialog controls whether the \f{Properties} or the \f{Select} (\K{cmdSelect}) command is used as the default command.
